Schema

A schema file defines the structure of data. It is a object array. A simple schema looks like this:

[
    {
        "key":"code",
        "type":"enum",
        "value":[-1,1,0]
    },
    {
        "key":"message",
        "type":"exactly",
        "value": "success" 
    },
    {
        "key":"lists",
        "type":"array",
        "length":10,
        "schema":[
            {
                "key":"id",
                "type":"index",
                "start":100,
            },
            {
                "key":"Week",
                "type":"enum",
                "value":["Mon","Tue","Wen","Thu","Fri"]
            }
        ]
    }
]

key and type is required for every object. key is the property name of data and type tells how to generate data. Currently, type is one of ['index', 'number', 'exactly', 'enum', 'word', 'sentence', 'date', 'object', 'array'], each type can have some other property.
